The age of great geographical discoveries

I would like to tell about great geographical discoveries because for me it is the most interesting theme in history and I don’t like reading about wars. I think it’s very important to know the great people who developed the history of Mankind.
One of the supreme geographical discoveries is Columbus’s voyage to the coasts of India to the west, through the Atlantic ocean. As a result of this journey a new continent was discovered, that now is called America.
